External tool content embedded in RCE gives 'Couldn't find valid settings for this link' error when copied with selective import or Copy To...


This behavior has been resolved and deployed to the production environment as of 6/27/24.


When content from an external tool is embedded in the RCE using a resource_link_lookup_uuid and the content is copied between courses using the Copy To... option or using the select specific content option in a course copy, the content will not display in the course it was copied into. Instead a ‘Couldn't find valid settings for this link’ error displays.

Expected Behavior

Instead content embedded from external tools in the RCE should successfully copy between courses when using the Copy To… option or selective imports.


No workaround exists at this time.

Steps to Reproduce

Prerequisites: Two courses in an account where an external tool is installed which can embed content in the RCE using a resource_link_lookup_uuid (the new lucid tool worked for me).

  1. In one of the courses create a page with content from the external tool embedded.

    1. The src for the tool iframe should be in the format

      Specifically without any url query param as Canvas will fall back to that to find a tool if looking up the tool via resource_link_lookup_uuid fails

  2. Copy the page to the other course using the Copy To… option.

  3. Open the page which was just created by the copy and note that in the place of the external tool content there is an iframe with the course home page and a flash warning stating 'Couldn't find valid settings for this link’
